Look for unfamiliar subjects on bikes or foot. Oftentimes burglars in these cases will be carrying backpacks.

Look for slow moving cars.

If you can do so safely:

Get a description of the vehicle, the driver, and occupant(s).

Try to obtain a license plate number.

If someone knocks on your door and you don't feel comfortable opening it, make sure they know you are home. Yell through the door that you are calling the police. If you don't let them know you are home, they may try to break in.

To avoid solicitors coming to your residence, get a sign that states, "No Soliciting".

If you are comfortable opening your door, always ask for credentials of solicitor(s) selling a product or service.

Don’t make posts on social networking sites which inform others when you will not be home.

When away from home for an extended period:

Make your home look as it usually does when you are there. Ask a neighbor to open and close drapes and blinds as you do.
